g SU3 PPOR'1ING.DEVICE FOR PLASTER-BOABDS USED IN PARTITION CONSTRUGTIGI-I.

.To all whom it may concern:

Be it known that I, MARVIN H. Jns'ren, a

' citizen of the United States of'America, re-

siding in the city and county of Denver and State of Colorado, have invented a new and usefulSupporting Device for Plaster Boards Used in Partition Construction, of

which the following is a specification.

of the plaster boards, U-shaPedclips'being placed upon the bars, having lateral wings which form backings for the ends of the. plaster boards, nails' being driven through apertures" in the bars and through registering horizontal slots in the clips, so as to bear against the outer faces of the adjoining ends of two boards, whereby the ends of thesaid boards are securely clamped between the nails and the wings of the clips, their adjoining ends abutting againstv the sides of the clip. I

These objects are accomplished by the device illustrated in the accompanying drawings, in which x 'Figure l, is a front elevation of a partition, showing plaster boards secured and supported by my improved device. Fig. 2, is an enlarged horizontal sectional view on the line 22 ofjiig. 1. Fig. 3, is a perspective viewfull sizesh'owing a portion of one of the upright bars, with aclamping device thereon, comprising a clip, and a hall, which pass through the bar and clip. Fig. 4, is a side view of the arrangement illustrated in Fig. 3. And Fig. 5, is a side view of a moditied form of clip.

Similar ietters of reference'refer to similar parts throughout the several views.

Referring to the accompanying drawingsThe numeral 1 designates the upright supports, which are preferably in the form of metal channel bars, and are secured at their ends to the floor and ceiling, the channel bar form of upright possessing the necessary strength and rigidity for the purpose required. These uprights arespaced at intervals corresponding to the length of the Specification of Letters Patent.

disposed with respect to the width of the Patented Jan. 12,

Application filed July 29, um. Serial m1 712,002.

plaster boards employed, which are usually thlrty-six lnches long by about thirty inches wide, with a thickness of about three-eighths of an inch. These boards 2, are laid one above the other, between the uprights, as shown in Fig. 1, their ends abutting against the said uprights, and they are secured thereto in the following manner. The web of each upright is provided with a plurality of holes 3, which maybe equi-distant, and so boards that two holes" occur at points be.

tween the end corners of each board, shown, the uprights being positioned with their side members facin toward the front we and rear respectively. pon the uprights,

at-pointscoincident with the'holes 3, are

placed clips 4, comprising U-shaped hers 5, the sides of which terminate in lateral wings 6, which lie at right angles to the 7 H3 said sides The depth ofthe U-sha ed. inenibers of the clips is equal to the wieth oi" the channel bar uprights, so that when the clips are placed upon the uprights their win s will substantially flush with the adjacent sidepf the uprights, as clearlyshown in. the dr' Tings. The U-shaped portions of the clip; i are adaptedto fit snugly upon the up right, and by bending the sides of these h shaped portions slightly toward each other, or soathat they converge, it will be necessary to spring the clips'in placing them onv the uprights, and they will thus be held in position upon the uprights by the resilient clamping engagement of their side members with the said uprights.

The U-shaped member 5 of each clip divided by a transverse slot 7', which ea tends through its closed end and into parallel sides to points adjacent to the wings 6, and when the clips are in position on uprights, the slots register with the holes 3., in the uprights, as will appear by refer once to Fig. 4.

which are ofslightly greater diameter than the diameter of the nails, are so positioned relatively to the Widths of the said .webs that where a nail is inserted in one of the holes 3, it will contact with the outer margin of the said hole, and With the adjoining ends of the boards, and'the head of the nail being .of greater diameter than its shank portion, its engagement'withthe plaster board will cause its shank to pass through the hole 3, at a slight angle to the axis of the said hole, thus converting the nail into a Wedge between which and the wings of the clips the ends of the boards arev secur ly clamped. The holes 3 may be pl ced any suitable dis-' tance from, either side of the center of the bar, so as to allow for varying thicknesses of plaster boards. l

In operation, the clips first sprung upon the uprights, with their slots registering with the holes in the s id uprights, and the plaster boards are placed between the pairs of uprights, with their adjoining end portions resting against the wings of the said clips, as shown in 2., theboards being placed one upon the other until they reach from floor to ceiling, the nails are driven through the uprights and through the slots inthe clips, as each board is placed in position, and thus clamp the adjoining ends of the boards in the mann r ab0v .d scribed. After the boards have been secured to the uprights, they are covered on their opposite sides with a coating of plaster or cement, after which the usual. finishing or smooth coating is applied, which completes the partition.

In Fig. 5, I have illustrated a modified form of clip 9, in which the sides of the U- shaped portion are provided with elongated holes 10, which take theplace of the slots 7 In other respects, this clip is the same as that shown in the other views.

Having described my invention, What I claim as new and desire to secure by Letters Patent, iszj v A supporting device for plaster-boards comprising an apertured channel-bar, a narrow vU-sha )'ed clip sprung over said channelbar havingin each leg an elongated slot parallel with the upper edge ofsaid clip and registering nvith an aperture of said channel-bar, wing-plates .on said clips adapted to lie behind the plaster-boards, and a wedge-member extending through said apertures and slots adapted to'engage and press inwardly on the plaster-boards along its end portions only and to efforts an outward pressure on said channel-bar at its center.

t In testimony whereof I ailixwny signature in presence of two witnesses.
